Speoication of Lettera Patent.

Patented Dec. 5, 1911.

Application illcd October 15, 1010. Serial No. 587,339.

To all whom it may concern:

Be it known that we, TRUMAN McCoRD and WILLIAM C. Blouin, citizens of the United States, residin at Rew, in the county of McKean an State of Penn lvania, have invented certain new and use ul Improvements in Well-Drilling Machines, of which the following is a specification,

reference-being had to the accompanying,

drawings.

This invention relates to improvements in pumping or drillin machines and has for its o ject to provi e an im roved support for an operating shaft inclu ing hollow metallic jack posts and means for ri idly mounting said posts upon a mud sill an for securing the shaft upon the upper end thereof. v A further object of the invention is to provide a very simple and easily arranged supporting structure for a crank shaft and one which is light and extremely rigid.

Another object is to (provide spaced tubular 'ack posts arrange in bearings upon a mud sill, bearing caps for a crank shaft arranged upon the upper end of the posts, and vertical tie rods extending through said posts, the mud sill and said caps to rigidl secure the crank shaft upon the upper ends7 of the posts.

With these and other objects in View, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanyin drawings, in whichigure 1 is a side elevation illustratin the arrangement of my improved j-ac posts; Fig. 2 is a 'vertica longitudinal section; Fig 3 is a section taken on the line 3 3- of ig. 2; and Fig. 4 is a top plan view.

Referring more particularly to the drawing 5 designates the mud sill which is ada ted to be arranged below the surface of t e groundA as shown in Fig. 1. Bearing plates 6 are arran eliupon the mud sill 5 and are formed 'wi anges 6 to rovide an extended bearing surface. hese bearing plates are formed with annular [langes 6* tro rrclive, the lower ends of the jack posts struction and are of suicient' le h 'to extend the desired distance above e ground surface. The posts 7 are rigidly connected intermediate o their ends or at about the -machines which is li ese posts are of hollow metallic conl ground level, by means of a bolt 8 which extends through the posts and has a nut 9 threaded on each end thereof.

Upon the upper ends of the jack posts 7 bearl ca s 9 are arranged, said caps having ro ata ly mounted in the bearing or-v tions 9 thereof, a crank shaft 10 whic is adapted to be connected to the walking beam of a drill or pum in the usual manner. Upon one end o the crank shaft a band wheel 11 is secured over which a suitable dr1v1n belt passes and extends to the motor or ot er source of ower. The bearin ca s 9 are rigidly he d Yupon the upper en s o the sill posts 7 by means of the tie rods 12 which extend vertically v'there throu h. The upper ends of these rods extend t rough the caps 9 and the lower ends thereof extend throu h o enings in the mud sill 5. Upon the en s o said rods the nuts 1:3 are threaded whereby all of the parts are rlgidly clamped together, said tie rods holding the posts .7 in the bearing plates 6 and the caps 9 upon theA upper'ends of said posts. As'shown in Fig. 3 two of the tie rods extend through each of the posts 7 and are arranged upon o osite sldes of the crank shaft 10, sald shafitllieing centrally mounted upon the bearin caps 9. Thus there is an egual pressure 0% the caps 9 u on all points o the upper end of the hol ow posts thereby obvlating the liability of weakenin the structure.

From t e foregoing it will be seen that we have devised a ver simple shaft supporting structure for rilling or pumping ht and comparatively inexpensive to manu acture. The posts may be easily and quickly arran ed in osition and by means of the connec ing bot 8 and the tie rods 1'2 it will be obvious that an extremely rigid structure is provided.

While we have shown and described the preferred embodiment of our invention, it will be understood that the device is susceptible of considerable modification Without departing from the essential feature or.

sacrificing any of the advantages thereof.

Hav'n thus described the invention what is claime isz- In a machine of the character described, the combination of a mud-sill s aced bearings arranged upon said sill, lio low metal'- lxc posts mounted in said bearings at their lower ends, bearing caps removably arranged upon the upper ends of said posts to support a. crank shaft thereon, a pair of spaced tie rods vertically disposed through each of said posts and extending at their upper ends throu h said bearin caps on opposite sides of t e crank sha t, the lower ends of seid tie rods extending through the bearings in which the posts are mounted and through the mud sill, said rods having nuts threaded upon their upper and lower ends to clamp the posts between the bearing caps and the lower bearings arranged on the sill, and a. horizontal bolt connecting said hollow metal posts and extendin through the same and between said vertioa tie rods, substantially as and for l the purpose set forth.

In testimony whereof we hereunto affix our signatures in the presence of two wit- Copies of this patent may be obtained for iviI cents each, by addressing the Commissioner of Patents. Washington, D. C.
